[C320-list] Clearing thru-hull obstruction

[resloat]

I would do the following:  get a small diameter piece of metal, plastic or 
wood; get some towels; check out how to take off the outlet hose from the 
through hull valve; loosen the two C clamps on the hose; gently turn the 
hose to remove it; push the obstruction back clearing the thru hull; then 
put everything together.  There is a plug on my thru hull valve that can be 
used to plug the outside of the thru hull.  If you are really worried about 
water getting in attach a line to it and try to plug the hole on the sea 
side of the thru hull.   Then when you push the obstruction out you can 
recover the plug.

This seems the easiest solution.  Just a screw driver, something to clear 
the obstruction and some towels.  Myself, just a screw driver and a #2 
pencil is all that is needed.  This all assumes there is an obstruction in 
the thru hull and no blockage in the fresh water strainer or elsewhere.
